Design of a microprocessor-based sphygmomanometer

Area of Science:

• Biomedical Engineering
• Medical Instrumentation
• Cardiovascular Physiology

Background:

• Accurate blood pressure measurement is crucial for diagnosing and managing cardiovascular diseases.
• Existing methods for blood pressure monitoring can be invasive or prone to errors.
• Automated and non-invasive techniques are sought to improve patient care and data collection.

Purpose of the Study:

• To develop and validate a new, microprocessor-based method for indirect measurement of systolic and diastolic blood pressure.
• To automate the blood pressure measurement procedure, reducing human error and increasing efficiency.
• To assess the accuracy and reliability of the developed device through clinical testing.

Main Methods:

• Implementation of a novel technique on a microprocessor for indirect blood pressure measurement.
• Statistical analysis of cardiac pulse pressure signals to derive polynomial relations.
• Development of an electronic analog-digital sphygmomanometer controlled by a microprocessor.
• Validation of the prototype through laboratory construction and clinical trials.

Main Results:

• A new method for indirect blood pressure measurement based on cardiac pulse signal analysis was successfully implemented.
• An automated, microprocessor-controlled sphygmomanometer was developed and constructed as a laboratory prototype.
• Clinical tests demonstrated that the device achieves accuracy within acceptable limits for automated blood pressure instruments.

Conclusions:

• The developed microprocessor-based system offers an accurate and automated approach to indirect blood pressure measurement.
• The statistical analysis of cardiac pulse pressure signals provides a reliable foundation for non-invasive blood pressure monitoring.
• This technology has the potential to enhance the diagnosis and management of hypertension and other cardiovascular conditions.
